Description

If your Polaris LX 600 shows signs of worn top-end components, you’ll know it—dropped throttle response, sluggish cold starts and rising engine temperature. This Complete Top End Rebuild Kit gives you the parts you need to bring back reliable performance without touching the full bottom end.

Inside this kit you’ll find Nikasil-plated cylinders, matched piston kits with rings, circlips and wrist pins, needle cage bearings and a dedicated top-end gasket kit. Together, these parts restore sealing surfaces, recover compression and eliminate the performance drag that comes from worn components. For riders comparing rebuild options, you may also explore our LX 600 Engine Rebuild Kit for a broader component package.

Every component is designed for snow conditions and long trail miles. Snowmobile riders who log serious terrain know these sleds respond sharply when the top end gets refreshed. If you have questions on install or fitment, our FAQ page offers quick answers.

This rebuild kit is backed by our 1-year, no-questions-asked warranty. Check the full coverage details in the warranty policy section. If you’re new to ordering parts online, the Help Center guides you through shipping and prep. Feel free to reach our support team anytime via our contact page, and for extra snowmobile performance insight, visit our blog.
